摘要：

The effect of focusing geometry oil slope of carrier-envelope (CE) phase phi(CE) versus propagation distance from the focus in few-cycle laser pulses is investigated. The slope could be adjusted by changing the distance L between the waist of the incident beam and the lens. At the focus, partial derivative phi(CE)/partial derivative 9(z/zr) = 0 when L = 0, and partial derivative phi(CE)/partial derivative(z/zr) = -2 when L = infinity. The longer the distance L, the steeper the curve of the CE phase at the focus.
